1 What does R look like?

Now, let’s open RStudio and see what it looks like.

When you open RStudio, you will see a screen like this one:

Click on the icon to get the screen with four sections and I’ll run you through all of them.

Now, you should see something like this:

You can change the settings in your computer to reorder the different sections, or to change the appearance of your screen.

2 Let’s get you acquainted

You should see 4 panes on your screen. We’ll talk about each one.

Pane 1: This pane holds your script, set of commands, or code. The script is your working document.

Add a title, your name, and a date. Use the hash tag (#) symbol to tell R that this is a reading text and not a command.
Save it to your computer as you would do with a word or excel file.

Let’s play with the basic features of RStudio and populate our first script.

Creating an outline 1. Create a title that reads “Part 1”. Use one hash tag symbol at the beginning and end with 4 dashes (- - - -).

Create a subtitle that reads “1.1 Writing a simple command” Now, use two hash tags at the beginning and, as before, end with 4 dashes (- - - -).
Look at the outline. This feature is very useful to navigate your script when it starts growing.

Let’s move on.
